HOUSING FOR TRACTION-ENGINE GEARING.

Specification of Letters Patent.

Application filed June 18, 1909.

Patented Apr. 23, 1912.

Serial No. 502,936.

To all whom it may concern:

Be it known that I, EDWIN M. WHEELOCK, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Housings for Traction-Engine Gearing, of which the following is a specification.

My invention relates to means for housing gearing, especially such as the driving gearing of traction engines.

The objects of the invention are to provide a casing for such gearing which shall be tight and dust proof and at the same time separable to give ready access to the inclosed parts, the casing being adapted to serve to hold a lubricant and supply the same to the inclosed gearing.

My improvements are illustrated in the accompanying drawings, in which- Figure 1 is an elevation of the inner side of one of the driving wheels of a traction engine embodying my improvements, parts being broken away. Fig. 2 is a horizontal section of the same on the line a-a of Fig.

1. Fig. 3 is a view from the left of Fig. 1,

and Fig. 4C is an enlarged detail view showing the manner in which the two parts of the gear housing are united.

In the drawings 1 designates a portion of the metal framework of a traction engine, on which are provided the journal-boxes 2 for the axle 8 of the driving-wheels. The hub 4 for the driving-wheel 5 and its driving gear-wheel 6, as shown in Fig. 2, consists of an integral body that carries both wheels. The portion of the hub that supports the driving wheel is providcd with two circular flanges 7 and 8 which line on converging lines, and to these the 1118i ends of the spokes are secured by rings 9.

The driving-gear wheel 6 is supportgi on the hub by means of radial arms 10 extending from the latter and attached by rivets 11 to lugs 12 formed on the inner surface of the gear-wheel rim. In this way the driving wheel and the gear wheel are rigidly and firmly joined, so that the rotation of the latter is communicated directly and positively to the former. The gear-wheel 6 is driven, as usual, by a pinion 13 on a driving shaft 14 that is journaled in boxes 15 on the frame, and the shaft is rotated by suitable connections (not shown) with the engine in the usual way.

The gear-wheel and the pinion are housed by a tight sheet-metal casing composed of a lower section 16 and an upper section 17 The casing is secured by angle-plates 18 to portions of the framework, the upper section being attached to the frame members 3 and the lower section to a bar 19 provided for the purpose. The upper member 17 is provided with a lap-strip 20 by which a recess or socket 21 is formed for receiving the top edge of the lower member 16 and make a close joint. A suitable lubricant 22 is placed in the lower section through which the teeth of the gear-wheel pass. Either casing member can be readily removed by unscrewing the screws by which the angleplates 18 are secured in place. Such casing serves not only to exclude dirt, dust, and water, but also affords as a convenient means for keeping the gearing properly lubricated and thereby increases its efliciency.

Having described my invention, what I claim and desire to secure by Letters Patent is 1. In combination, a supporting framework, a gear casing comprising a lower portion secured to a portion of said framework, and an upper portion provided with means adapting the same to be removably secured to said framework, said upper portion being provided with a lap strip extending about the margin thereof in parallel spaced relation to said margin so as to form a socket for receiving the upper edge of said lower half of the casing thereby to form a tight joint therewith.

In combination, a supporting frame work, a two-part casing, an auxiliary frame piece to which one portion of said casing is permanently secured, the other portion of said casing being removably secured to the main framework, said removable portion being provided with a lap-strip surrounding the margin thereof in parallel two subscribing Witnesses this 3d day of spaced relatiion with the Walls of said mar- June, 1909.

in so as to orm a socket for receiving the dge of said first named portion of the cas- EDWIN WHEELOOK ing thereby to form a tight joint therewith. \Vit-nesses:

In testimony whereof I have signed my P. H. GUNGKEL, name to this specification in the presence of H. A. BOWMAN.
